RECEIVING DEVICE AND OPTICAL SWITCHING FABRIC APPARATUS
First Claim
1. A receiving device, comprising:
- at least two selecting modules, each selecting module configured to receive a multiwavelength optical signal, filter a first optical signal of a set time segment from the multiwavelength optical signal, and output the first optical signal;
a fast optical switch connected to each of the at least two selecting module, the fast optical switch configured to receive each respective first optical signal, select a second optical signal from each respective first optical signal filtered by the respective selecting module, and output the second optical signals;
an output module connected to the fast optical switch, the output module configured to receive the second optical signals and combine the second optical signals separately selected by the fast optical switch into one optical burst signal, and output the optical burst signal; and
a receiver connected to the output module, the receiver configured to receive the optical burst signal, perform optical-to-electrical conversion on the optical burst signal to obtain an electrical signal, extract service data from the electrical signal, and output the service data.

Abstract
The present invention provides a receiving device and an optical switching fabric apparatus, where the receiving device includes: multiple selecting modules, a fast optical switch connecting to each selecting module, an output module connecting to all the fast optical switches, and a receiver connecting to the output module, where the selecting module is configured to receive a multiwavelength optical signal, select and filter a first optical signal of a preset time segment in the multiwavelength optical signal; the fast optical switch is configured to select a second optical signal from the first optical signal filtered by the selecting module; the output module is configured to combine optical signals separately selected by all the fast optical switches into one optical burst signal; and the receiver is configured to perform optical-to-electrical conversion on the optical burst signal, and extract service data from an electrical signal.
